It's taken the internet a day or two (you're slipping, internet!), but the code that was posted on Deus Ex: Human Revolution's in-game main menu on Monday has finally been solved by some evidently rather clever people.

We're not sure quite how the decoders have done it (or, indeed, who exactly they are), but the long and short of it comes down to this Blue's News post (via VG247) and culminates in the website 13311tower.com.

Apparently some Morse code and GPS coordinates can be pulled from the site's code, with the Morse code revealing the line “11m13clinic” and the GPS coordinates pointing to Ayers Rock on Google Maps (also known as Uluru in Aboriginal legend).

When used as a password and username respectively, “11m13clinic” and “uluru” unveil the static image shown above-right on the 13311tower.com site (simply click on the All Seeing Eye Illuminati Post-it image on the right-hand site of the splash page to prompt a log-in box).

Effectively though, this leaves us all none the wiser despite all the ARG chasing. The “Sun 04:28:56” reference in the bottom-left of the image could point towards another reveal time this weekend, although that's a bit of a leap really.

VG247 claims that it's all an elaborate tease in the lead-up to a DLC announcement that could add an episode featuring J.C. Denton (the original Deus Ex protagonist). The site's source claims that players are prompted to choose a new augmentation setup rather than import a Human Revolution save file to the DLC.

More detail from the rumour suggests that the new content will be staged on a ship, and that none of the communication support available to Adam Jensen in the main game will be present in this DLC. We'll bring you more as we get it but don't pin too many hopes on these rumours just yet...
